Illinois Car Sales Tax: Chicago, Cook County, and the RUT-50 Trap
A car registered in Chicago pays 9.75 percent sales tax since August 1, 2026. That is 7.5 percent state and transit, 1 percent Cook County and 1.25 percent city use tax, and a city sticker of $105.18 a year follows. Buy from a private seller instead and the percentage is replaced by a flat RUT-50 amount, $850 at $15,000 and $2,600 at $50,000, plus Cook County's $90 to $225 by the car's age.
A vehicle titled to a Montana LLC pays Montana's fees instead, $899 the first year through Zero Tax Tags. What Illinois asks of a car that is kept and used in Illinois depends on where it actually lives; the page below walks through every layer, the county differences and the Montana route.
What is the sales tax on a car in Illinois? It depends on where you register it, not where you buy it. The state’s base rate is 6.25 percent. A car registered in Chicago pays 9.75 percent since August 1, 2026: the state-and-transit rate of 7.5 percent for Cook County, plus 1 percent Cook County use tax and 1.25 percent city use tax. Suburban Cook County pays 8.5 percent, the collar counties 7.25, Madison and St. Clair 6.5, and the rest of the state 6.25. Buy from a private seller and the percentage disappears: Illinois charges a flat amount from the RUT-50 chart, $850 at $15,000 and $2,600 at $50,000 on the 2026 chart, plus a Cook County flat tax of up to $225. Then the plates: $151 a year, $251 for an EV, a $165 title, and in Chicago a $105.18 city sticker every year.
At a glance (rates since August 1, 2026):
- Dealer purchase, by the address you register at: Chicago 9.75%, suburban Cook County 8.5%, DuPage, Kane, Lake, McHenry and Will 7.25%, Madison and St. Clair 6.5%, everywhere else 6.25%.
- Trade-in: the full value comes off the taxable price at a dealer (the $10,000 cap ended in 2022); none on a private sale.
- Private sale: a flat amount from the 2026 RUT-50 chart, $465 down to $100 by age under $15,000, then $850, $1,100, $1,350, $1,600, $2,600, $5,100 and $10,100 by price; Cook County adds $225, $175 or $90 by age.
- Every year: $151 registration, $251 for an electric vehicle, and a Chicago city sticker of $105.18 or $167.07 by weight.
- Montana LLC: $899 the first year and $270 a year after through ZeroTaxTags; on a qualifying sale to a Montana purchaser an Illinois dealer collects no Illinois tax (ST-58 reciprocal, Form ST-588).
The Marcus Chen Story: A $92k BMW and Three Tax Surprises
Illinois car sales tax is the kind of bill that arrives in pieces. Marcus Chen, a 41-year-old commercial litigator at a LaSalle Street firm in Chicago, learned this the hard way on a Saturday in August. He had finally pulled the trigger on a 2025 BMW M5 sedan, sticker price $92,400, after months of test drives and spreadsheet justifications. The deal at the dealership in River North went smoothly. He had pre-approved financing through his credit union. He had run the math himself: 6.25 percent state sales tax on $92,400 came out to $5,775. He budgeted $6,000 to be safe.
Then the finance manager slid the paperwork across the desk and pointed at a line item that said $9,009 in tax. Marcus did the quick mental math. That was 9.75 percent, not 6.25. He asked what happened. The finance manager explained, almost apologetically, that the state’s 6.25 percent is only the first line. The state rate for a car registered in Cook County is 7.5 percent once the transit share is in, Cook County adds a 1 percent use tax of its own, and the City of Chicago adds 1.25 percent on any titled vehicle registered to a city address. All of it is keyed to the Lincoln Park address on his driver’s license, not to the dealership. The 9.75 percent was correct. There was no mistake. He was paying $3,009 more in tax than he had budgeted, because of where he lives. Marcus signed. He drove home.
Six weeks later a notice from the City of Chicago landed in his mailbox. Wheel tax, which the city sells as a vehicle sticker. A hundred and sixty-seven dollars, the large-passenger rate, because the current M5 weighs more than 4,500 pounds. Annually. Every single year that this BMW is registered to his Chicago address. Marcus had never paid a wheel tax in his life. He had grown up in Naperville. He had no idea Chicago charged residents a flat annual fee on top of state registration just for the privilege of keeping a car within city limits. He paid it. He muttered something unprintable about Cook County, opened a beer, and moved on.
The third surprise came two months after that, when his law partner mentioned offhandedly that he had bought a used Porsche Cayenne for $48,000 and the Illinois Secretary of State had collected a tax bill of $1,600 with the title. Marcus, who deals with tax law regularly enough to feel insulted, asked how that was calculated. His partner pulled out the form. RUT-50. Private party use tax. The amount had nothing to do with the 9.75 percent that Marcus had paid. It was a flat-rate bracket from a printed chart issued by the Illinois Department of Revenue, collected by the Secretary of State when the title changes hands. Plus $225 because Cook County tacked on a flat tax of its own for a car under four years old. That was when Marcus, quietly furious for three months, started Googling Montana LLC registration at 11:47 p.m. on a Tuesday.
That Google search is what brought a lot of Illinois drivers to this page. Sales tax on a car in Illinois is not a single tax. It is four taxes stacked on top of each other, and depending on where you live and how you bought the car, the order in which they hit you changes. This article is the explainer Marcus wishes he had read before he signed.
How Illinois vehicle tax actually works: the four-layer stack
Most states charge one vehicle tax. Maybe two. Illinois charges four, and the difference between the cheapest and the most expensive Illinois zip code is enough to fund a week-long vacation every year. To understand the Illinois vehicle sales tax burden, you have to understand each layer separately and then watch them combine.
Layer one is the state sales tax, plus transit. Illinois charges 6.25 percent on the purchase price of any vehicle bought from a licensed dealer, and it is the same in Carbondale and in Evanston. Where you register the car adds the next slice, because the regional transit districts ride on the same return: the Department of Revenue sets the rate at 7.5 percent for a car registered in Cook County and 7.25 percent in DuPage, Kane, Lake, McHenry and Will, both up a quarter point since August 1, 2026, and 6.5 percent in Madison and St. Clair. On a $50,000 truck the base rate is $3,125; registered in Cook County it is $625 more, in the collar counties $500 more, in Madison or St. Clair $125 more. Simple, predictable, and not the part that is going to ruin your day.
Layer two is the county and city use tax. This is where Illinois gets weird. Municipal and county home rule sales taxes do not apply to a titled vehicle, so Cook County and Chicago each pass a use tax instead: Cook County takes 1 percent on a vehicle registered to a Cook County address, and Chicago takes 1.25 percent on titled property registered inside the city (Municipal Code 3-28). Dealers anywhere in the six-county area collect both on the state ST-556 return, and they go by the buyer’s address, not the showroom’s. So if you live in Wilmette and buy in Chicago, you pay Wilmette’s 8.5 percent, and a Chicago resident who drives to Naperville to buy still pays 9.75.
Layer three is Cook County’s flat tax on private sales. Buy a car from a person rather than a dealer and Cook County adds a fixed amount to whatever the state RUT-50 chart says: $225 for a vehicle one to three years old, $175 for four to eight, $90 for nine and older, $25 for a gift. Since 2015 the state collects it with the title. It is separate from the state private party tax and separate from the city sticker. It exists because Cook County figured out that vehicle transfers were a revenue stream nobody was taxing twice.
Layer four is the annual wheel tax, which Chicago sells as the city vehicle sticker. This is the one that catches people off guard the most. A passenger car of 4,500 pounds or less costs $105.18 a year, a heavier passenger vehicle $167.07, and the fees move with inflation each January. Some other home rule suburbs charge their own wheel taxes too; Evanston charges $90. This is not a one-time fee at purchase. It is a recurring annual cost for as long as you own the car and live in the jurisdiction. Ten years of Chicago stickers on an ordinary car is more than $1,050 at today’s rate. Twenty years is more than $2,100. It adds up quietly.
And underneath all four layers sits the standard Illinois registration fee, $151 a year for a passenger car and $251 for an electric vehicle, plus a $165 title fee at purchase. Layer five, if you want to count it. Most people don’t. They are too busy being shocked by layers one through four.
One piece of good news, because there is not much of it. Since January 1, 2022 the full value of a trade-in comes off the taxable price at a dealer again; the $10,000 cap that applied in 2020 and 2021 is gone (Form ST-556 instructions). On a private sale there is no trade-in deduction at all.
Chicago vs. collar counties vs. downstate: the same car at three prices
The geographic premium on Illinois car sales tax is real and measurable. Two identical vehicles bought on the same day at the same dealership can carry a four-figure difference in tax, because the rate follows the address the car is registered at, and the city line runs through the middle of the Chicago suburbs. The math is straightforward but the practical impact is brutal, especially on luxury and performance vehicles where the percentages translate to bigger absolute dollars.
Consider the same $60,000 SUV registered at three different Illinois addresses. Registered in Chicago, the buyer pays 9.75 percent, $5,850. Registered in Naperville, in DuPage County, the buyer pays 7.25 percent, $4,350. Registered in Springfield or Bloomington, the rate is the bare 6.25 percent, $3,750. The Chicago premium on a $60,000 vehicle is $1,500 compared with the collar counties and $2,100 compared with downstate, and the suburban Cook buyer in Evanston or Oak Park sits in between at 8.5 percent, $5,100. On a $120,000 vehicle every one of those gaps doubles.
| Vehicle price | Chicago (9.75%) | Suburban Cook (8.5%) | DuPage and the collar counties (7.25%) | Downstate (6.25%) | Chicago vs downstate |
|---|---|---|---|---|---|
| $40,000 | $3,900 | $3,400 | $2,900 | $2,500 | +$1,400 |
| $60,000 | $5,850 | $5,100 | $4,350 | $3,750 | +$2,100 |
| $90,000 | $8,775 | $7,650 | $6,525 | $5,625 | +$3,150 |
| $120,000 | $11,700 | $10,200 | $8,700 | $7,500 | +$4,200 |
| $150,000 | $14,625 | $12,750 | $10,875 | $9,375 | +$5,250 |
That table only shows the at-purchase tax. It does not include the city sticker, which adds $105.18 every year for Chicago residents on top of the state registration fee. Over a five-year ownership period the sticker alone adds $526 to the cost of keeping an ordinary car within Chicago city limits, $835 for anything over 4,500 pounds. For households with two or three cars, the math gets ugly fast.
One tax people mistake for an Illinois tax: the gas guzzler tax. It is federal, it applies only to passenger cars, never to SUVs or trucks, with a combined rating under 22.5 mpg, the manufacturer pays it, and it is already inside the window-sticker price, between $1,000 and $7,700 depending on the rating. Illinois has no fuel-economy or luxury vehicle tax of its own. What it has is a 9.75 percent rate on a Chicago-registered car, which on a $120,000 sedan is $11,700 before anyone mentions the sticker, and that is enough to make most New Yorkers wince.
The private party bracket trap: RUT-50 and the $15,000 cliff
If buying from a dealer in Illinois feels expensive, buying from a private party introduces a whole different kind of pain. Illinois does not charge a percentage tax on private vehicle transfers the way most states do. Instead, the state uses a printed flat-rate chart tied to either the vehicle’s purchase price (for vehicles $15,000 and up) or the vehicle’s age (for vehicles under $15,000). The form is called RUT-50, it must be filed within 30 days of purchase at a Secretary of State office along with the title transfer, and the Department of Revenue reissues the chart each year; the 2026 chart runs January 1 through December 31, 2026.
For vehicles priced under $15,000, the tax is set by age, and the 2026 chart reads like this:
- one year old or newer, $465;
- two years, $365;
- three years, $290;
- four years, $240;
- five years, $190;
- six years, $165;
- seven years, $155;
- eight years, $140;
- nine years, $125;
- ten years, $115;
- eleven years or older, $100.
This system was designed in an era when cars depreciated faster and used vehicles under $15,000 dominated the private market. It still works for that segment, though a hundred dollars on a fifteen-year-old pickup is not nothing.
For vehicles $15,000 and up, the system gets weird. Illinois uses a flat-rate price bracket that pays no attention to the actual purchase price within each bracket:
- $15,000 to $19,999.99, $850;
- $20,000 to $24,999.99, $1,100;
- $25,000 to $29,999.99, $1,350;
- $30,000 to $49,999.99, $1,600;
- $50,000 to $99,999.99, $2,600;
- $100,000 to $999,999.99, $5,100;
- $1,000,000 or more, $10,100.
Motorcycles and ATVs are a flat $25, a transfer from a parent, child, spouse or sibling is $15, and no trade-in comes off any of it.
The bracket trap works like this. If you buy a used $25,500 Audi Q5 from a neighbor, you owe $1,350. If you instead negotiate the price down to $24,999, you owe $1,100. A $501 reduction in purchase price triggers a $250 reduction in tax, an effective marginal tax rate of nearly 50 percent on that last dollar. People who shop carefully on the bracket boundaries can save real money. People who don’t pay extra for nothing.
The trap bites hardest at $50,000. A $49,999 car pays $1,600. A $50,000 car pays $2,600. One dollar of price, a thousand dollars of tax. The same thing happens again at $100,000, where the bracket jumps from $2,600 to $5,100. Marcus’s law partner, who paid $48,000 for his Cayenne, was $2,000 under the cliff and never knew it. Most private party buyers do not even realize they are in a bracket system until the Secretary of State prints out the bill.
And then Cook County adds its flat tax on top of the state amount, $225 for a car under four years old, just because you happen to live in Cook County. For a car under four years old, the combined private party hit on a $25,000 to $49,999 used vehicle in Cook County runs $1,575 to $1,825; an older car pays the county $175 or $90 instead, so the floor drops to $1,440. That is before you have registered the car or paid the city sticker. Illinois private party vehicle tax is one of the least understood private party tax structures anywhere, and there is no trade-in deduction against it.
The 30-day filing deadline matters. If you miss it, Illinois assesses penalties and interest. The Secretary of State can also block your title transfer if RUT-50 is not filed and the tax not paid. There is no grace period for “I didn’t know.”
5-year cost tables: Illinois vs. Montana LLC
The case for Montana LLC registration is not theoretical. It is arithmetic. Below is the five-year cost comparison for a Chicago resident at three different vehicle price points, using the 9.75 percent rate on a city-registered car, the $105.18 annual city sticker, and Illinois registration fees on the Illinois side, and the standard Montana LLC pricing of $899 in year one and $270 per year thereafter on the Montana side.
| Cost item | $60k vehicle | $90k vehicle | $120k vehicle |
|---|---|---|---|
| Chicago sales tax (9.75%) | $5,850 | $8,775 | $11,700 |
| 5 yrs IL registration ($151) | $755 | $755 | $755 |
| 5 yrs Chicago city sticker ($105.18) | $526 | $526 | $526 |
| 5-yr Illinois total | $7,131 | $10,056 | $12,981 |
| Montana LLC year 1 ($899) | $899 | $899 | $899 |
| Montana years 2-5 ($270 x 4) | $1,080 | $1,080 | $1,080 |
| 5-yr Montana LLC total | $1,979 | $1,979 | $1,979 |
| 5-year difference | $5,152 | $8,077 | $11,002 |
Note that the difference does not include the Cook County flat tax on a private party purchase ($225 for a car under four years old), or the time and frustration of standing in line at the Secretary of State office to file RUT-50 paperwork. It also assumes you keep your vehicles for five years. Many luxury vehicle owners turn over their cars every two to three years, in which case they pay the full Chicago rate repeatedly. The Montana LLC pays once and then maintains forward.
Who gets hit hardest: four Illinois profiles
Not everyone in Illinois feels the car tax the same way. The pain is concentrated in four specific buyer profiles, and if you recognize yourself in any of them, you are probably overpaying by thousands of dollars per year compared to what your neighbors in Indiana or Wisconsin pay for the exact same vehicles.
Profile one is the Chicago luxury buyer. This is the resident of Lincoln Park, the Gold Coast, River North, the South Loop, Bucktown, Wicker Park, or any of the dozen other Chicago neighborhoods where high-income professionals concentrate. They buy German sedans, British SUVs, Italian sports cars. They are the buyers most likely to pay the full 9.75 percent rate and the most likely to be locked into the annual sticker forever. A Chicago dermatologist with a $130,000 Mercedes-Benz S-Class pays $12,675 in sales tax at purchase and $167.07 every single year, the large-passenger sticker because the car weighs more than 4,500 pounds, as long as the car is registered to her Chicago address.
Profile two is the private party used car buyer anywhere in the state, but especially in Cook County. This is the person who bought a low-mileage 2018 Porsche Macan from someone on Facebook Marketplace for $35,000 and is now staring at a RUT-50 form with a $1,600 tax bill plus a $175 Cook County add-on, $1,775 in all. The percentage they are effectively paying is more than 5 percent of purchase price, but because Illinois doesn’t call it a percentage tax, most buyers don’t realize how steep it is until they are at the Secretary of State counter writing the check. Private party buyers also have no opportunity to roll the tax into financing because most credit unions and banks do not finance private party purchases the way dealerships do.
Profile three is the fleet or multiple vehicle owner. This is the family or small business that has more than two registered vehicles. Maybe a primary commuter sedan, a family SUV, a teen driver’s used car, and a project car or weekend toy. Maybe a contractor with three work trucks. The Chicago wheel tax compounds across vehicles. Three ordinary cars in a Chicago household equals $316 per year in stickers alone, $1,578 over five years, before any registration fees or sales taxes. For business owners with five or more vehicles, the math gets seriously punishing.
Profile four is the suburban commuter who bought before they realized. This profile catches a lot of people moving into Chicago from the suburbs or out of state. They register their existing vehicles at their new Chicago address, file the use tax forms, and then discover they now owe annual wheel tax forever. Or they bought their car years ago in Naperville at the lower suburban rate and then moved to the city, where the annual wheel tax now applies even though they did not pay it on the original purchase. There is no grandfathering. The wheel tax is location-based, not purchase-based.
The Montana LLC solution: how it actually works
Montana is a state with no general sales tax. Montana also allows non-residents to form limited liability companies, and Montana LLCs can own, register, and title vehicles within the state. When a Montana LLC owns a vehicle, that vehicle is registered in Montana, gets Montana plates, and pays Montana’s fees. At the dealership, Montana is a reciprocal state on the Department of Revenue’s ST-58 chart, so on a qualifying sale to a Montana purchaser an Illinois dealer collects no Illinois sales tax when the purchaser signs the ST-588 nonresidency certification and the vehicle leaves on a drive-away permit or Montana plates. No ST-556 tax and no Cook County or Chicago use tax at the sale. That rule covers the sale itself. Whether any Illinois or Chicago charge still reaches a vehicle titled to a Montana LLC later, the city sticker included, depends on where the vehicle is actually kept and used.
The mechanics are simple. We form a Montana LLC in your name. The LLC owns the vehicle on paper. The vehicle is registered to the LLC’s Montana address with the Montana Motor Vehicle Division. You receive Montana plates by mail. You drive the car wherever you actually drive it, including Chicago, the suburbs, downstate, anywhere. The registration is real, the LLC is real, the title is real. The savings are real because Montana simply does not have the layered tax system Illinois has built up.
Year one cost is $899 total. That breaks down as $699 for our service (LLC formation, registered agent setup, Montana DMV paperwork, plate delivery) and $200 in actual Montana state filing fees and registration costs. Year two and every year after is $270, which covers the registered agent service and the Montana annual report. There is no per-vehicle add-on like Chicago wheel tax. The same $270 covers the LLC for as many vehicles as you choose to register through it.
Compared to the cost of paying full Illinois tax on a single $90,000 luxury vehicle, the Montana LLC pays for itself before the tires hit the driveway. Compared to a household with three or four vehicles, the savings compound into territory that genuinely changes financial outcomes. We have clients who have saved $30,000 over a decade by routing every vehicle purchase through their Montana LLC instead of through the Illinois Secretary of State.
Is this actually legal? Direct answer.
Yes, as far as Montana is concerned, and that part is not a gray area. A Montana LLC can be formed by someone who lives elsewhere, it can own a vehicle, and Montana titles and plates the vehicles its LLCs own. Every piece of the structure is a public filing: the LLC with the Montana Secretary of State, the title with a Montana county treasurer, the plate issued to the company.
What Montana does not decide is what Illinois asks of a vehicle that is kept and used in Illinois. Whether a vehicle titled to a Montana LLC still owes Illinois use tax, the Chicago and Cook County add-ons or the wheel tax is Illinois’s question, and the answer depends on where the vehicle actually lives, not on the plate. The Louisiana Supreme Court’s decision in Thomas v. Bridges is often cited here; it held that the member of a properly formed Montana LLC was not personally liable for Louisiana use tax on a motorhome the LLC bought. It did not decide what any state may ask of a vehicle kept and used within its borders.
The structure fits owners whose vehicles genuinely travel: RV owners on the road for months at a time, second-home owners, collectors whose vehicles go to shows and auctions, and businesses that operate across state lines. If you are not sure whether your situation fits, call us and we will tell you honestly.
Three Illinois case studies
Illustrative examples. The situations below are composites of common Illinois cases, not specific customers. Vehicles, prices and tax figures are real and current; the people are not individually identified. Your own costs depend on your county rate, your vehicle and your paperwork.
Real numbers tell the story better than tables can. Here are three composite cases that mirror conversations we have weekly. The math is what a household in each position would save.
Case Study 1: The Chicago attorney with the $92k BMW M5
Marcus, 41, partner-track litigator in River North. Bought a 2025 BMW M5 sedan for $92,400. Registered to his Chicago address, the 9.75 percent rate would have meant $9,009 in sales tax, plus $151 a year in registration, plus $167.07 a year for the city sticker for as long as he owns the car. Through Montana LLC registration his year-one cost was $899 total, his ongoing annual cost is $270, and over a five-year ownership horizon he comes out roughly $8,600 ahead even after the LLC service costs. He told us he would have happily paid double for the peace of mind alone.
Case Study 2: The Naperville dentist with the used $68k Porsche Cayenne
Priya, 38, oral surgeon in DuPage County. Found a private party 2022 Porsche Cayenne S in Schaumburg for $68,000. On the 2026 RUT-50 chart a purchase between $50,000 and $99,999 is a flat $2,600, and because she lives in Naperville, not Cook County, there is no county flat tax and no city sticker, just the $165 title and $151 a year for plates. Through her Montana LLC the year-one cost was $899 instead of $2,600, an immediate $1,701, and over five years she is about $1,500 ahead once registration is counted. Smaller than the Chicago BMW client, but a higher percentage saving on a private party transaction, and the kind of buyer who routinely shops private party sees it on every deal.
Case Study 3: The Schaumburg couple with the $110k motorhome
David and Linda, 62 and 60, semi-retired empty-nesters in Schaumburg. Bought a $110,000 Class A motorhome for cross-country trips. Registered in suburban Cook County the rate is 8.5 percent, $9,350 in Illinois sales tax, before five years of Illinois RV plates, which are priced by weight. Through Montana LLC registration their five-year total was $1,979, so they came out more than $7,300 ahead on the sales tax alone, used a portion of it to buy a tow vehicle, and registered that under the same LLC without forming a second one. They take the motorhome to Florida every winter and have never had a registration problem in any state they have driven through.

Frequently asked questions
How much is sales tax on a used car in Illinois?
From a dealer, the same rate as a new car, set by your registration address: 9.75 percent in Chicago, 8.5 in suburban Cook County, 7.25 in the collar counties, 6.25 downstate. From a private seller there is no percentage: the 2026 RUT-50 chart charges a flat amount, $465 down to $100 by age for cars under $15,000 and $850 up to $10,100 by price above that, and Cook County adds $225, $175 or $90 by age.
Do I pay Illinois tax if I buy a car in another state?
Yes, if you register it in Illinois. You file Form RUT-25 within 30 days and pay the rate for your address, with a credit for any sales tax the other state collected. Buying in Indiana or Wisconsin does not get a Chicago resident out of the 9.75 percent; it only changes who collects it.
Is a trade-in taxed in Illinois?
Not at a dealer, not since January 1, 2022. The full trade-in value comes off the taxable price; the $10,000 cap that applied in 2020 and 2021 was repealed. On a private-party purchase there is no trade-in deduction at all, because the RUT-50 tax is a flat amount that ignores what you traded.
Do I need to physically visit Montana?
No. The entire process is done remotely. We are your registered agent in Montana, which is the legal address requirement. You do not need to travel, take time off work, or set foot in the state. Plates and documents come to wherever you actually live. Most of our Illinois clients never set foot in Montana before, during, or after the process and never need to.
Will Illinois find out and come after me?
Anyone who runs the plate sees a valid Montana registration in the LLC’s name, because that is what it is. Whether Illinois can ask anything of the vehicle beyond that depends on where it is actually kept and used, which is a separate question from the registration. The structure is built for owners whose vehicles genuinely travel; it is not a way to hide a vehicle that never leaves Illinois.
What about insurance?
Standard auto insurance works fine. You insure the vehicle the same way you would any other car. Some major insurers will issue policies directly to the LLC. Others will issue policies to you personally with the LLC listed as the lienholder or owner. We provide guidance on which carriers handle this most smoothly, and we have clients with Geico, Progressive, State Farm, Liberty Mutual, USAA, and several specialty insurers, all working without issue.
Can I sell the vehicle later?
Yes. The LLC is the owner of record, so the LLC sells the vehicle and signs the Montana title over, which is faster and simpler than an Illinois title transfer. The buyer pays whatever their own state charges on a used-car purchase; an Illinois buyer files RUT-50 and pays the flat chart amount, exactly as they would buying from any out-of-state seller. Illinois has no seller-side tax on a private sale.
Does this work for multiple vehicles?
Yes. One Montana LLC can own as many vehicles as you want to register through it. The same $270 annual fee covers the LLC regardless of how many vehicles are titled to it. Clients with three to six vehicles see the most dramatic savings because the fixed LLC cost gets spread across more vehicles. The marginal cost of adding a sixth vehicle to an existing LLC is essentially just the Montana state registration fee for that vehicle.
What if I get pulled over in Illinois?
You show your Illinois driver’s license, the Montana registration card in the LLC’s name and your proof of insurance, the same as anyone driving a company-owned vehicle. Out-of-state plates are an everyday sight on Illinois roads.
What about tolls and red light cameras?
Toll authorities and camera-ticketing systems will look up the registered owner, which is your Montana LLC. The LLC receives the toll bill or ticket at its Montana address, which is forwarded to you. You pay normally. There is no enforcement gap, and we provide guidance on setting up automatic I-PASS or E-ZPass under the LLC name so you avoid the manual processing.
Does this work for leased vehicles?
Generally no. Leased vehicles are owned by the leasing company, and the leasing company decides where the vehicle is registered. They typically register it to your home address. Montana LLC registration works for vehicles you own outright (cash purchase) or finance through standard auto loans (where you are the title-holder, not the leasing company). For most luxury buyers this is not a constraint because they are buying, not leasing.
What about EVs? Does Illinois have an EV registration penalty?
Yes, since 2020. Illinois charges $251 a year to register an electric vehicle against $151 for a gas car, and the Chicago sticker applies to both. Montana has its own annual fee on top of registration, $130 for a battery-electric under 6,000 pounds and $70 for a plug-in hybrid (MCA 61-3-572). An EV registered to a Montana LLC still comes out well ahead of Illinois on any vehicle priced over about $30,000, because the purchase tax is where the money is.
How quickly can you get me started?
Same day if you are ready. We file LLC paperwork the same business day we receive your application and payment, and the full process from application to plates in your hand typically runs 14 to 21 days. If you are about to close on a vehicle purchase and need to coordinate timing, contact us first and we will work backward from your closing date to make sure the LLC is ready when the dealer cuts the title.
